RAILWAY SIGNAL-TOBPEDO.

v Application filed October 18, 1918. 7 Serial No. 258,715.

To all whom it may concern I Be it known that I, FRANK DUTOHIER, a citizen of the United States, residing at Versailles, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Railway Signal-Torpedoes, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates. to improvements in railway signal torpedoes, and pertains to that type of torpedo which has become known to the trade as paper or nonflying. 7 i I The object of the present improvement is to provide a novel way of attaching the rail-engaging strap to thetorpedo, and a novel way of preventing the strap from having a longitudinal or end-wise movement in respect to the torpedo case.

In the accompanying drawing-- Figure l is an enlarged inverted perspective view of a railway torpedo with my im provement applied thereto.

Fig. 2 is a vertical transverse sectional view of the invention. c

Fig. 3 is a detached perspective view of the ring which forms the side wall of the case and the rail-attaching member.

Fig. 4 is a perspective view of the ring which forms the side wall. of-the case, showing a modified construction of the mannor of attaching the rail-engaging member. Fig. 5 is a detached perspective view of the rail-attaching member shown in Fig. 4.

In carrying out my present improvement, I prefer to use a circular fiat form of torpedo case, though the shape of the torpedo may be varied without departing from; the spirit and scope of the present improvement. In fact, the case may be rectangular in plan View, or any other shape to which the improvement is adapted.

The case here shown, comprises a fibrous or paper ring 1, a fibrous orpaper disk 2 forming the to of the case, a fibrous or paper disk 3 forming the bottom of the explosive-carrying case. and below the disk 3 is a third disk 4-, all the disks being made of fiber or paper.

The ring and disks are preferably waterproof in any suitable manner and the explosive 5 is between the disks 2 and 3. This explosive is preferably of the tablet form.

Specification of Letters Patent.

Patented Mar. 1, 1919 The ring 1 is provided with a narrow pcripheral bur or fiange'6 at each" edge, and

these flanges serve to support the disks within the ring 1. Thus far I have described a construction of torpedo which, is disclosedand claimed in my co-pending application, filed October 18th 1918, Serial No. 258,714, and, therefore, no claim is made in this application to the construction of the torpedo case per 86, as that is the subject-matter ofthe above numbered co-pending application.

In my present improvement the rail -engaging member 7 passes through suitablyshaped openings 8 in the ring 1, and between the disks 3 and 4C. To make'the joints be: tween the peripheries of the disks 2 and 1 and the ring water proof, I place a'suitable quantity of water-proof cement 9 u at. that point, which also serves to assist the flanges 6 in holding the disks withinthe ring. [-1 As here shown, the openings 8 are in the formcof notches made in the lower edge of the ring 1, though other formsofopenings may be made, through whichthe strap or rail-engaging "member 7 passes and still be w1th1n the generic 1I1V6I1l310n here .d1sclosed.

For the purpose of preventing the railengaging member or strap ,7 from being pulled longitudinally through the case, I provide the member 7 with shouldersadapted to engage or interlockorabut against the ring 1 and prevent the longitudinal move-, ment of the strap or member 7.. I

In Figs. 1, 2 and 3-, Ishow one form of shoulder to abut against the ring, which'is formed by depressing themember7, just inside of the ring, thus forming shoulders 10 which will abut against the ring and prevent the longitudinal movement thereof, as will be readily understood.

In Figs. 4 and 5, I show a modification in the manner of forming shoulders on the member or strap 7 which consists in providing the strap or member with notches 11, and making the notches 8 narrower than the member 7, so that the notches interlock with the ring and will abut thereagainst to prevent the stra from having a longitudinal movement.

While I have shown the shoulders 10 located within the side wall or ring 1 of the case, and preferably so located, it will be understood that the shoulders can be formed outside of 'tllG'IlIig and perform the same function of preventing longitudlnal movement of the strap or member 7.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. An improved railway signal torpedo, comprising an explosive containing case, and a rail-engaging member passing below the bottom of the case and through the side wall ofthe case.

2. An'improved railway signal torpedo comprising an explosive containing case, a strap passing through the side wall of the case and below "the bottom and connected thereto; the rail-engaging member having shoulders "adapted to abut against the side wall of the case to prevent longitudinal movement of the rail-engaging member.

3. An improved railway signal torpedo,

, comprising an explosive containing case, the

sidewall of the "case having oppositely arranged openings 'below the bottom of the explosive containing case, a rail-engaging member passing through the openings and connected with'the said bottom;

4:. An improved railway signal torpedo 6. An improved railway signal torpedo,

comprising a case having a double wall botthrough the side wall of the case, between the walls of the bottom, and having shoulders adapted to engage the side wall of the case to prevent the longitudinal movement of the rail-engaging member.

8. An improved'railway signal torpedo comprising an explosive containingjcase, a side wallofthe case'having oppositely arranged notches, a rail-engaging strap passing through the'notches and against thebottom, means for'ho-lding the rail-engaging member against the said bottom, the railengag'ing member having shoulders formed by depression andadapted to engage the side wall of the case to prevent longitudinal movement thereof. I i

9. An improved 'railwaytorpedo comprising an explosive containing case, composed of airing and disks within the ring forming a bottom and "a top for the case, the ring extending below the said bottom and provided with openings and a rail engaging member passing through the openings below and attached to the said bottom.

10. An improved railway signal torpedo comprising a case composed of a ring and two disks, one formi'ng'the top and the'other the bottom of the explosive containing case, said ring projecting below the bottom and having oppositely arranged openings, arailengaging member passing through the open ing and against the bottom,' and a third disk below th rail-engaging member and serving toconnect it to'the said'bottom.

In testimony whereof I hereuntoaifix my signature in thepresence of two witnesses.
